V = (4/3) pi  r^3

9.  V = (4/3)(3.14)(7.62)^3 = 1852.4  meters^3
10. V = (4/3)(3.14)(33/2)^3 = 18,807.0  inches^3
11. V = (4/3)(3.14)(18.4/2)^3 = 3260.1  feet^3
12. V = (4/3)(3.14)(sqrt3)/2)^3 = 2.7 cm^3
13. C = 2*pi*r ;   24 = 2 * 3.14 * r;   24/6.28 = r ; r = 3.82
   V = (4/3)(3.14)(3.82)^3 = 233.4 in^3
14.V = (4/3)(3.14)(35.8)^3 = 192,095.6  mm^3

I can't read # 15 but follow the steps above.

Sophie deposited money into an account in which interest is compoundedsemiannually at a rate of 2.4%. She made no other deposits
meriva

Given

Compounded semiannually

rate = 2.4%

time = 11 years

Future Value = $11,227.78

\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ \frac{A}{(1+\frac{r}{n})^{nt}}=\frac{P(1+\frac{r}{n})^{nt}}{(1+\frac{r}{n})^{nt}} \\ P=\frac{A}{(1+\frac{r}{n})^{nt}} \\ P=\frac{11227.78}{(1+\frac{0.024}{2})^{2(11)}} \\ P=\frac{11227.78}{1.012^{22}} \\ P=8636.20 \end{gathered}

Rounding to the nearest whole number, the amount the she has deposited is $8636.

A school cotains 357 boys and 323 girls if a student is chosen at random, what is the probability that it is a girl
solong [7]

Answer:

P(G)=0.475

Step-by-step explanation:

From the question we are told that:

Number of boysN_b=357

Number of girls N_g=323

Total Number of students

N_t=N_b+N_g

N_t=680

Generally the equation for Probability of Choosing a Girl is mathematically given by

P(G)=\frac{N_g}{N_t}

P(G)=\frac{323}{680}

P(G)=0.475

Write the standard form of the line that passes through the given points (6,1) and (5,4)
Serggg [28]

The standard form:

Ax+By=C

The point-slope form:

y-y_1=m(x-x_1)

m - slope

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (6, 1) and (5, 4). Substitute:

m=\dfrac{4-1}{5-6}=\dfrac{3}{-1}=-3

y-1=-3(x-1)      <em>use distributive property</em>

y-1=-3x+3          <em>add 1 to both sides</em>

y=-3x+4         <em>add 3x to both sides</em>

\boxed{3x+y=4}
